background program or service interrupts active program

I bought a HP Pavilion Sleekbook 15 which came with Windows 8. My problem is that in both Windows 8 and 8.1 when I have a program open, something is interrupting the program. The title at the top of the program dims showing it's not the active program for about half a second before resuming. It does this all the time and interferes when I try to type anything. I have not figured out what the problem is. I thought at first it was 8.1 so reverted to windows 8 and then reinstalled the entire system. It still happens. I cannot figure out what is causing the interference. Someone suggested it might be a compatibility issue with Windows 8 and 3rd party programs.

I think I'd try booting without all the HP software. Windows 8.x will run just fine without it. Click Start and type MSCONFIG in the search box, then run it. Click the Startup tab (Note: don't use the other tabs) and you'll see a list of programs being started when you boot. You can uncheck everything there except your antivirus software. Then reboot and see if that fixes the problem.

If you still have problems, I'd run SFC. To do that go to Start and type CMD in the search box. Right-click CMD.EXE and click Run as administrator. From the Command Prompt type sfc /scannow. That will check for and attempt repair of any corrupt system files.

Good luck.

Everyone with a computer should back his system up to an external hard drive regularly.
